It's a rare thing to catch Senator Ted Cruz looking sheepish. There have been no documented cases since he swaggered onto the public stage during the 2012 Republican primary looking cocksure despite plenty of occasions (see: shutting down the government) where it might have been appropriate to show some regret.
Yet the junior senator from Texas does in fact feel shame, or at least can contort his face into an expression that suggests he does. The nation's Filipino World War II veterans have provided us with video proof.
Rewind one week, if you will, to the closing minutes of Cruz' 21-hour anti-Obamacare not-exactly-a-filibuster, when he said this:
I don't want to miss the opportunity within the limited amount of time is imperative that I do, which is to thank the men and women who have endured this, this Bataan Death March.

The veterans of the real Bataan Death March, during which several hundred American and several thousand Filipino POWs died during a forced, abuse-filled 80-mile trek, were not pleased to have their ordeal likened to the relatively minor and completely self-inflicted discomfort of an Ivy League lawyer.
Cruz, recognizing that his day-long monologue aimed at enraging people who disagree with him had also inadvertently insulted decorated World War II veterans, the most politically sacrosanct voters in America, quickly moved to make amends. The vets did the nation another service and posted it to YouTube.
